remove prototypes with no matching function and externs with no var
partly checked by millert@

Remove unnecessary #ifdefs in telnet. No binary change.

Eliminate a pile of casts that were superfluous or wrong, or that were
the result of bad type choices, particularly (unsigned char *) vs
(const char *). Also, use reallocarray().

use ansi style function declarations

Eliminate silly call() routine that fakes up internal calls as if
the user typed in undocumented arguments by splitting two functions
and doing normal (shock!) C calls.

Mark a slurry of functions as static
Eliminate two more trivial wrappers

Kill lint comments; mark ExitString() as __dead

VSUSP and SIGTSTP are required by POSIX

Add prototypes to some function callbacks and fix the type errors that
this reveals.
Make NetTrace static to utilities.c

More encryption tentacles: intr_happened and intr_waiting vanish
Push more includes into .c files
Make ring.c only need ring.h

Eliminate trivial wrappers TerminalWrite() and TerminalRead()
Replace TerminalFlushOutput() with tcflush().
Replace TerminalAutoFlush() with check of tty's NOFLSH flag as
documented in the manpage.

Simplify #includes, start pushing them into the .c files, eliminate
extern declarations from .c files that duplicate those in .h files,

remove a variable called wantencryption.
hahahahahahahahahha. OK, I'm done.

Flense the telnet code base of unwanted ifdefs: authentication/encryption
tn3270, sgtty, pre-POSIX and other ancient system support, etc. Brings up

Only use setsockopt(..SO_RTABLE..) if the -V flag is given to nc/telnet,
same style as traceroute6 (change to int and use -1 as a flag, so rtable 0
can still be used as an explicit parameter).

Fix the naming of interfaces and variables for rdomains and rtables
and make it possible to bind sockets (including listening sockets!)
to rtables and not just rdomains. This changes the name of the
system calls, socket option, and ioctl. After building with this
you should remove the files /usr/share/man/cat2/[gs]etrdomain.0.

Since this removes the existing [gs]etrdomain() system calls, the
libc major is bumped.

Last but not least. Telnet -V rdomain to connect to systems in other routing
domains.

- only send exported vars (based on a diff from Solar Designer)
- fix some buffer overflows (also some Solar Designer input)
